Specific embodiment
The technical solution of the utility model, but protection domain of the present utility model are described in further detail below in conjunction with the accompanying drawings
It is not limited to as described below.
As shown in figure 1, a kind of waste gas cleaning system for removing toluene, it include containing the workshop 1 of toluene gas, air-introduced machine 2,
Cooled lauter tub 3 and purification barrel 4, the top in the workshop 1 containing toluene gas are provided with the draught hood 5 of taper, are set on draught hood 5
Air outlet is put, the air inlet of air-introduced machine 2 is connected by airduct with the air outlet of draught hood 5, the air outlet of air-introduced machine 2 passes through air inlet
Pipe 12 is connected with cooled lauter tub 3, and the bottom of purification barrel 4 is provided with air inlet 41, and top is provided with exhaust outlet 42；
Cooler 6 is provided with described cooled lauter tub 3, ethanol solution, cooled lauter tub are housed in cooled lauter tub 3
3 top is provided with air outlet, and the air outlet of cooled lauter tub 3 is connected by airduct with the air inlet 41 of purification barrel 4, air inlet pipe
12 end is inserted in ethanol solution, and cooled lauter tub 3 is sealing；
As shown in Fig. 2 being provided with the suction sheet 8 of polylith parallel arrangement in described purification barrel 4 from bottom to top, inhale
Tag 8 is made up of the network 9 on purification barrel 4 and the adsorbed film 10 being fixed on network 9, on adsorbed film 10
Toluene adsorption particle is attached with, described toluene adsorption particle is activated carbon granule, modified honeycomb coal particle etc..
As shown in figure 3, being provided with annular slot 11 corresponding with suction sheet 8, network on the described inwall of purification barrel 4
